RGB Ambient Lighting (hopes/dreams)... pre-facelift Golf Mk7

[Cuzoe]

Okay so starting to answer some questions... they are RGB. And I guess since you can change the colors we know you have them connected to LIN bus.

In the process of doing this retrofit, i have found that the info you posted above is not a 100% rule. I even have a pretty unorganized spreadsheet where I was testing the various LEDs I have on hand to see what group they belong to and how they can be assigned.

For example, 8W047355 K + L are Group_01 as you mention. But they can be assigned as door, middle console, instrument panel, or speaker. With any of those assignments the lights work and they respond to the "sun" for that zone.

I don't know when/if I will ever find or allocate the time continue testing but I have in my garage some of the part numbers you mentioned. I did not know what group all of them belonged to. But based on the info you provided, I can narrow down my testing to just seeing what zones they can be assigned to. Previously I would have to go through and figure out the groups first.

I have not been able to find a description for the error channels anywhere and I don't have any interest in testing it. But since you can assign a given group to a number of different zones I figured it was more simple (on a car that does not have RGB OEM) is to just disable all of the error channels. I will know if one of my RGB LEDs is not working.

If you have LEDs with no letter at the end of the part number you could disable all the groups then re-enable and one at a time to confirm their GROUP. And then you would have to assign that group to something (door for example) and that would be the only place you could install those LEDs.

Misread the partnumber, it's 3G0927103..

Haha, well that would have saved us some time . The Ali listing shows them as "door" lights for "all MQB" which doesn't mean much considering what we know. But since they are being sold as "door" lights I assume they all belong to one group... just gotta figure out which group.

So, I finally went through all the lights I have, both installed and not installed.

Light Group	RGB LED Part Number	Install Location (in my car)	Function Assignment	Verbauinfo_HMI (sun icon)	Alt functions I've tested.
01	8W0 947 355 K	Middle Console Area	Center console	HMI_1 00010000	Door, Instrument, Speaker
04	8W0 947 355 J	Not installed yet (dash strip likely)	N/A	N/A	Door, Instrument, Console
07	8W0 947 355 C	Front Door Strip	Door	HMI_2 00010000	Instrument, Console
08	8W0 919 390 B	Front/Rear Door Pockets	Door	HMI_2 01000000	Instrument, Console
09	8W0 947 355 E	Not Installed	N/A	N/A	Door, Roof
10	8W0 947 355 F	Not Installed	N/A	N/A	Door, Roof
12	8W0 947 355 G	Front Door Handles	Door	HMI_2 00000100
12	8W0 947 093	Front Door Handle (hold)	Door	HMI_2 00000100	Console
12	8W0 947 094	Front Door Handle (hold)	Door	HMI_2 00000100	Console
13 & 14	8W0 947 415 (A - D)	Footwells	Footwell	HMI_1 00000100

First note, this is just how I've installed RGB LEDs in my car, and their groups. This is not an exhaustive table for what LEDs belong to which group, or all the functions a given group can be assigned. In researching this whole RGB LED thing I kept finding "mismatches" in the various coding/install guides. Well, it turns out that some RGB LEDs can be assigned to different groups depending on the function. And some RGB LEDs seem to have a hard group assignment. And in most cases a given group, although it can be assigned any function, will not actually work for all functions.
- For example, "footwell" light 8W0 947 415 D (likely A, B and C as well) will operate as Door light under Group 12 if Group 13 and 14 are set to "NOT-DEFINED"
- Other examples are that many lights cannot be assigned to the Roof function.

Another note, about why I "grouped" Group 13 and 14... RGB footwells require coding that does not make sense to me, but is required for them to work. Not included in the table is a channel named "verbauinfo_gruppe_x" which in most cases is set to "multicolor." For whatever reason, verbauinfo_gruppe_13 must be set to "single color" and verbauinfo_gruppe_14 gets set to to "NOT-DEFINED" to get RGB footwells working.

Watching this thread and done some of the stuff.
But can’t activate the “sun” for AID…
I still have the old slider for instruments.

But new menu for colour in AID/info
And slider for doors and footwell

Anyone with some help?

Also, will it be possible after LIN and new lights to have blue AID and other colours in footwell?
